Factoring Trinomials Whole Group Practice

We are in the process of learning to solve quadratics by factoring. I am taking it slow and starting from the ground up with my students. We started with “find two numbers that…” I made it more of a riddle. I worked, one at a time, on the problems on the top of the first page of the freebie. We talked about how integers work, ie if you multiply two numbers and get a negative, what do we know about the signs of those numbers? One is positive and one is negative. If you add those two numbers and get a positive answer, what do you know about those two numbers? The bigger number has to be positive and the smaller number is negative. If you add and get a negative number, what do you know? The bigger number is negative and the smaller number is positive. If you multiply two numbers and get a positive what do you know about the the signs of those two numbers? They are both positive or both negative. If you add two numbers and get a positive answer what do you know about the signs of those numbers? They are both positive. If you add those two numbers and get a negative, what do you know about those two numbers? They are both negative. Understanding the number sense of integers makes a big difference!

These are two pages that I started with on factoring trinomials. Sorry this post is so short and without photos, but I am SWAMPED and wanted to share some of the stuff I have been doing. I have a ton more, so the next few posts may be short and sweet with a freebie. Don’t hate me….. lol! Basically, these are just organized notes and practice problems that I did with my classes. Use them how you see fit. Thanks for your loyalty. Click here or on the image below to download the great freebie! Let me know what you think in the comments! This was just the very first of our learning to factor trinomials…. there is more to come……
